I have been looking for a short sleeved, long pant, cotton jumpsuit forever & this one fit perfectly! Easy on/off & will be great for travel. (I prefer rompers & jumpsuits for travel cuz they're one piece.) I'm 5'7, 125 pounds & the medium fits perfectly so I'd say possibly size up for most people. It just so comfy & cute & I can't wait to travel in it this summer!
